Abstract
In this study, we evaluate the Volt- VArand Volt-V AR-Watt functions of smart inverters based on the PV penetration level (PVPL) and the photovoltaic (PV) curtailment. The Volt- VArand Volt- V Ar- Watt functions are compared with the optimal control parameters that maintain the distributed network voltage within an admissible range and minimize PV curtailment. The study results at each PVPL (0-100%) with a typical distribution network model highlight the following points within our conditions. (1) Optimal control parameters vary with the PVPL and two weather conditions; (2) The maximum PVPL does not reach 100% with the Volt-V Arfunction, whereas the Volt-VAR-Watt function enables the maximum PVPL to reach 100%; and (3) the Volt-VAR-Watt function curtails PV generation, and the average ratio of PV curtailment on cloudy and sunny days is about 12.1 % and 0.16%, respectively.
在本研究中,我们基于光伏渗透水平(PVPL)和光伏(PV)削减来评估智能逆变器的Volt- var和Volt- v AR-Watt功能。将Volt- var和Volt- V - Ar- Watt函数与使分布式电网电压保持在允许范围内并使光伏减容最小化的最优控制参数进行了比较。在我们的条件下,典型配电网模型在每个PVPL(0-100%)下的研究结果突出了以下几点。(1)最优控制参数随PVPL和两种天气条件的变化而变化;(2)使用伏特-伏特-瓦特功能时,最大PVPL不能达到100%,而伏特-伏特-瓦特功能可使最大PVPL达到100%;(3)伏-变-瓦函数限制光伏发电,阴天和晴天平均削减比例分别约为12.1%和0.16%。
